Middle and low-voltage lateral adaptive contact power acquisition device

Abstract

The invention relates to a middle and low-voltage lateral adaptive contact power acquisition device, in particular to an automatic power acquisition device which works by electric power from a power grid in a rubber-tyred container gantry crane (RTG) of a large freight yard in a port. A plurality of upright columns are arranged in a direction of an RTG running track in the center of a dummy road in a container yard, bridge members are arranged between the upright columns, two power supply trolley lines are arranged laterally on the bridge members, and a photoelectric detection plate for guiding an RTG cart to travel is arranged in parallel to the power supply trolley lines so as to guide and control the RTG for automatic deviation rectification and keep a distance for power acquisition. The lateral adaptive contact power acquisition device is arranged at a lower transom side of the RTG, and a power acquisition arched plate of the adaptive contact power acquisition device adjusts contact force for power acquisition and is in flexible contact with the power supply trolley lines so as to laterally acquire direct power feed from the power supply trolley lines for operation of two groups of a plurality of RTGs on two sides. The device has high efficiency and safety in use, simple manufacture, convenient transportation, easy installation and low cost.

Description

technical field [0001] The invention is novel and practical, and relates to an automatic power-taking device for medium and low racks which is operated by grid power for container gantry cranes in large cargo yards of ports and wharves. Background technique [0002] The tire gantry cranes (RTG) in the large container freight yards of major ports at home and abroad all use diesel generator sets as power. Although the transition is flexible, the effective utilization rate of diesel generator sets is very low, only about 25%, and the reactive power consumption is large, and the fuel consumption is amazing. Noisy, environmental pollution, especially in the situation of energy shortage and rising oil prices, the use cost of tire gantry cranes is increasing continuously, while the price of electricity is relatively stable and the cost is low. "Change to electricity", using commercial electricity to drive the rubber-tyred container crane to operate, to reduce operating costs, reduc...

Problems solved by technology

[0002] The tire gantry cranes (RTG) of large container yards in major ports at home and abroad all use diesel generator sets as power. Although the transition is flexible, the effective utilization rate of diesel generator sets is very low, only about 25%, and the reactive power consumption is large, and the fuel consumption is astonishing. Noisy, environmental pollution, especially in the situation of energy shortage and rising oil prices, the use cost of tire gantry cranes continues to increase, while the price of electricity is relatively stable and the cost is low. "Change to Electricity", use commercial electricity to drive tire-type container cranes to operate, reduce operating costs, reduce air pollution emissions, reduce noise requirements, and achieve the purpose of saving energy and cleaning the environment

[0003] There are many ways to "change oil to electricity": elevated trolley lines, low-line safety slides, cable reels, etc. The container crane transfer is the most convenient, but the investment cost is high; the low-level safety slide line and cable reel method have less investment cost, but need auxiliary personnel to help the transfer, and the efficiency is low
